A control device for controlling power delivered to an electrical load includes a faceplate subassembly and a main control module. The faceplate subassembly includes a faceplate, a button, a circuit board, and a back cover. The faceplate includes a front surface and an opposed rear surface, and an opening extending therebetween with the button disposed in the opening in the faceplate. The back cover is positioned adjacent to the circuit board and defines a plurality of holes. A shaft of a post extending from the faceplate is disposed in one of the holes in the back cover and an end of the post is enlarged such that the back cover is captured between the end of the post and the rear surface of the faceplate. The main control module is configured to cause power delivered to the electrical load to be adjusted in response to depression of the button.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The control device of claim 1, wherein the faceplate includes a lip around a perimeter of the faceplate, the lip defining a depth, and wherein a distance between the front surface of the faceplate and a plate of the back cover is less than the depth of the lip.
3. The control device of claim 1, wherein the rear surface of the faceplate includes a recessed portion, and wherein the circuit board and the back cover are positioned at least partially within the recessed portion of the rear surface.
4. The control device of claim 1, further comprising a cable coupled to the local control module and the main control module to electrically connect the local control module and the main control module.
5. The control device of claim 1, wherein the main control module subassembly is configured to be mounted to a wall box via at least one screw, and wherein the faceplate subassembly covers the at least one screw when mechanically connected to the main control module subassembly.
6. The control device of claim 1, wherein the faceplate subassembly further comprises an attachment member coupled to the back cover, and wherein the attachment member is configured to couple the faceplate subassembly to the main control module subassembly.
7. The control device of claim 6, wherein the main control module subassembly further comprises a mounting bracket attached to the main control module, and wherein the attachment member includes at least one flex arm configured to engage the mounting bracket to couple the faceplate subassembly to the main control module subassembly.
9. The control device of claim 8, wherein the shaft and the flange portion of a respective post is created by cutting a groove in the post.
10. The control device of claim 1, wherein the diameter of the end of each post is made larger than the diameter of the respective shaft by forming the end of the post.
11. The control device of claim 10, wherein each of the plurality of posts includes a fillet at an interface of the shaft of the post and the rear surface of the faceplate.
12. The control device of claim 11, wherein each of the plurality of posts includes an internal bore that extends partially through the respective shaft from the end of the respective post.
13. The control device of claim 1, wherein the main control module is configured to be connected to a communication link and comprises an actuator, the main control module subassembly configured to transmit, via the communication link, a message indicating an actuation of the actuator.
14. The control device of claim 13, wherein the main control module comprises a visible indicator configured to illuminate to provide feedback.
15. The control device of claim 14, wherein the main control module is configured to disable operation of the actuator and the visible indicator when the faceplate subassembly is installed on the main control module assembly.
16. The control device of claim 1, wherein the faceplate subassembly further comprises a carrier positioned between the rear surface of the faceplate and the circuit board, wherein the carrier defines a second plurality of holes, each hole of the second plurality of holes aligned with one of the plurality of holes defined by the back cover, and wherein respective shafts of each of the plurality of posts is disposed in a corresponding one of the second plurality of holes in the carrier.
17. The control device of claim 16, wherein the carrier defines a button aperture, and wherein the button is at least partially disposed in the button aperture.
18. The control device of claim 17, wherein the carrier includes at least one protrusion extending into the button aperture and engaged with a notch in the button to limit rotation of the button with respect to the carrier.
19. The control device of claim 18, wherein the button includes a diffuser portion coupled to the cap portion, and wherein the notch is in the diffuser portion of the button.
